Abstract
The utility model relates to a self-riveting silicon steel sheet, which comprises a first surface and a second surface opposite to each other. A riveting buckle is punched on the self-riveting silicon steel sheet. The riveting buckle comprises a first riveting surface which is formed on the first surface and is inwardly recessed on the first surface, and a second riveting surface which is formed on the second surface and is outwardly protruded on the second surface. The first riveting surface forms a recess inwardly recessed on the first surface. The second riveting surface forms a protrusion outwardly protruded on the second surface. The first riveting surface is the same in shape with the second riveting surface. When two self-riveting silicon steel sheets are riveted, the protrusion of the first self-riveting silicon steel sheet is clamped in the recess of the second self-riveting silicon steel sheet, and the first riveting surface of the first self-riveting silicon steel sheet is tightly close to the second riveting surface of the second self-riveting silicon steel sheet, so that the two self-riveting silicon steel sheets are connected in a clamping manner. As the self-riveting silicon steel sheet provided by the utility model adopts the riveting buckle capable of riveting the silicon steel sheets into an integrated iron core, the iron core is convenient and rapid to assemble; and the assembled iron core has flat surface and good uniformity of electric performances.
